 DETAILED DESCRIPTION
While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.
The present invention provides a novel and efficient single-handed extendable cosmetic applicator designed to advantageously, conveniently, safely, and effectively extend and retract an applicator stem, having an applicator surface, with a single hand of a user. Embodiments of the invention also provide users the ability replace or exchange the cosmetic liquid contents in the applicator in an efficient and effective manner.
Referring now to FIGS. 1-2 and FIGS. 5-7, one embodiment of the present invention is shown. Said figures and others herein show several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a single-handed extendable cosmetic applicator 100, as shown in figures, includes an applicator body 102 and a cosmetic applicator stem 700 that is operably configured to extend and retract from the applicator body 102 for use by the user. Although the applicator 100 is beneficially configured for use with a single hand of a user, the applicator 100 may also be operable with two hands of a user and is otherwise not limited as such unless explicitly provided for in the body of the claims.
More specifically, the applicator body 102 may include a first body shell portion 110, a second body shell portion 114, and a third body shell portion 116 that enable grasping by the user, in addition to safe and efficient for storage, transportation, and use. The applicator body 102 may also include a selectively removable cover 104 disposed at a second end 108 of the applicator body 102, wherein the cover 104 may be operably configured to be removed (either completely or partially, and rotatably and/or linearly) from the second end 108 to expose a second opening 204 defined by the applicator body 102, e.g., a part of the third body shell portion 116. The second end 108 opposes a first end 106 of the applicator body 102 to define an applicator length separating the first and second ends 106, 108 of the applicator body 102. To enable the most effectively handling, the applicator length may be approximately 4-6 inches and may weigh approximately 0.1-0.75 lbs. Other lengths and weights may be contemplated, however, depending on material specifications and design constraints.
The first body shell portion 110 includes a sidewall 500 surrounding and defining, with an inner surface 504 of the first body shell portion 110, a first body shell cavity 502. As used herein, the term “wall” is intended broadly to encompass continuous structures, as well as, separate structures that are coupled together so as to form a substantially continuous external surface. The second body shell portion 112 may then be rotatably coupled to the first body shell portion 110 using a tongue-and-groove configuration, e.g., snap-fit. In some embodiments of the present invention, the second body shell portion 112 is also operably configured to be locked longitudinally with respect to the first body shell portion 110. The second body shell portion 112 also has a first end 612, a second end 614 opposing the first end 612 of the second body shell portion 112, and a sidewall 600 with a first portion 602 disposed within the first shell cavity 502. The sidewall 600 also includes a second portion 604 having an outer surface 114 and an inner surface 606. The inner surface 606 opposes the outer surface 114 of the second body shell portion 112 and defines a second portion cavity 608. As seen in the figures, the shell portion 112 may have a diameter separating two opposing outer surfaces that is greater than a diameter separating two opposing outer surfaces on the shell portion 110. The second body shell portion 112 may define (at least partially) an enclosed aperture 610 spatially coupling the enclosed aperture 610 to the first body shell cavity 502, wherein the enclosed aperture 610 serves as space for entry and egress of the cosmetic stem 700.
With reference to FIG. 1 and FIG. 4, the outer surface 114 of the second body shell portion 112 may also beneficially include a plurality of raised surfaces 400 a-n thereon to enable effective and safe rotation of the second body shell portion 112 with respect to the first body shell portion 110. To facilitate in single-hand rotation, the plurality of raised surfaces 400 a-n may span longitudinally on the outer surface 114 and may each respectively define a recess 402 therein between. In one embodiment, the raised surfaces may be approximately 0.025-0.1 offset from the outer surface 114.
With reference to FIG. 1 and FIGS. 5-7, the cosmetic applicator stem 700 may have a lower end 702 disposed in the first body shell cavity 502, an upper end 704 opposing the lower end 702 of the applicator stem 700, and a portion 1000 spanning through the enclosed aperture 610 defined by the second body shell portion 112. The cosmetic applicator stem 700 includes another portion 1002 that may be coupled to the second body shell portion 112, e.g., through one or more applicator guide member(s) 716, 718 that may be coupled to the stem 700 or a coupler 720 that may selectively removably (and potentially, frictionally) coupled to the stem 700. The applicator guide member(s) 716, 718 beneficially project radially from the cosmetic applicator stem 700 and may be disposed on opposing sides of the applicator stem 700 and/or the coupler 720. The cosmetical applicator stem 700 may be of a substantially rigid, yet flexible, material that enable minimal flexion when subjected to forces of approximately 1-2 lbs. In one embodiment, the stem (and the components coupled directly thereto) may be of a polymeric material such as polyoxymethylene (POM). In other embodiments, the material may vary.
The cosmetic applicator stem 700 beneficially includes an applicator surface 706 defined by a distal end of a plurality of bristles 708 a-n radially extending outwardly from an outer surface 710 of the applicator stem 700. In other embodiments, the applicator surface 706 may be formed from another surface or surface(s), e.g., a sponge material or a cosmetic material. The plurality of bristles 708 a-n may be of a polymeric and flexible material, e.g., nylon, rayon, silicon, plastic, and rubber. In preferred embodiments, the applicator surface 706 circumferentially spans around at least 50%, e.g., 100% (as shown best in FIG. 14), a perimeter of the outer surface 710 of the applicator stem 700 to provide effective application of the cosmetic liquid or material to the user regardless the orientation of the applicator surface 706. Because the applicator 100 may be operable for utilization with different cosmetic materials, the applicator surface 706 may be selectively removably coupled and locked to the cosmetic applicator stem 700 using, for example, a tongue-and-groove configuration 800 (as shown best in FIG. 8).
With reference to FIGS. 9-11, the second body shell portion 112 is operably configured to rotate about a longitudinal axis 900 along a rotation path (exemplified with arrows 902, 904) to cause linear and longitudinal translation (the direction of which is exemplified with arrow 1100) of the cosmetic applicator stem 700 through the second opening 200. Said differently, to enable linear translation of the cosmetic applicator stem 700 the second body shell portion 112 may be rotated in a clockwise or counterclockwise direction, thereby causing the applicator stem 700 to be moved in various linear positions. As such, the user is only required to keep his or her hand in one location on the applicator 100 and cause translation of the cosmetic applicator stem 700, e.g., with a user's fingers. Some of the linear positions of the applicator stem 700 may include a storage position (shown best in FIG. 10) with the applicator surface 706 housed or encapsulated within the applicator 100, e.g., within a third body shell cavity 304 defined by the sidewall 300 that surrounds, with an inner surface 302 thereon, the third body shell cavity 304.
With reference to FIGS. 4-7 and FIG. 9, in one embodiment, the container 100 includes a double-helix shaped channel 404 defined by the sidewall 500 of the first body shell portion 110 and which spans in the longitudinal direction of the container 100. The first portion 602 of the sidewall 600 may also define two stem translation channels 410, 412 that are disposed within the first shell cavity 502, wherein the two applicator guide members 716, 718 that project radially from the cosmetic applicator stem 700 are at least partially disposed, respectively, within the two stem translation channels 410, 412 and the double-helix shaped channel 404. As such, the rotation path (exemplified with arrows 902, 904) is operably configured to cause rotation of the cosmetic applicator stem 700 through the second opening 200 the rotation of the two applicator guide members 716, 718 around the double-helix shaped channel 404. The movement of the applicator stem 700 linearly (represented with arrows 1200, 1300) using said double-helix shaped channel 404 can also be seen in FIGS. 12-13. In one embodiment, the two applicator guide members 716, 718 oppose one another. Said another way, the two applicator guide members 716, 718 may be oriented and configured approximately 180° with respect to one another. The two stem translation channels 410, 412 may also oppose one another and have a linear and longitudinal oriented section 616 flanked by and spatially coupled to two linear and transverse oriented sections 618, 620. As such, the two applicator guide members 716, 718 are prevented from extending a particular length (depicted in FIG. 11 with arrow 1102) passed the second end 108 of the applicator body 102.
In another embodiment, the cosmetic applicator stem 700 may be translated and extended or retracted from the applicator body 102 with a threaded coupling configuration. More specifically, and using structural components of the cosmetic device 100 depicted in FIG. 11, the inner surface 1104 of the second body shell 112 may define a threaded configuration that is complementary to a threaded configuration defined by a portion of an outer surface 1106 of the cosmetic stem 700. The cosmetic stem 700 may be longitudinally and/or rotational biased and/or partially restricted, e.g., using a spring, to facilitate in moving the cosmetic stem 700 linearly caused by rotation of the second body shell 112.
Now with reference to FIGS. 2-3, the third body shell cavity 304 can be seen beneficially housing a liquid substance 306, e.g., mascara, therein for applying to, and/or absorbing with, the applicator surface 706. Specifically, the third body shell portion 116 has a sidewall 300 surrounding and defining, with an inner surface 302 of the third body shell portion 116. In one embodiment, the third body shell cavity 304 may house approximately 3-5 ml of a liquid substance therein. In other embodiments, another volume may be utilized. The third body shell portion 116 also includes a bottom surface 312 defining an enclosed aperture 314, a first end 308, and a second end 310 opposing the first end 308 of the third body shell portion 116. As best seen in FIGS. 10-11, the first end 308 of the third body shell portion 116 is selectively removably couplable to the second end 614 of the second body shell portion 112 with a tongue-and-groove configuration, e.g., a threaded configuration.
As the third body shell portion 116 may be selectively removable and replaceable with another cosmetic substance, the third body shell portion 116 beneficially includes a plug 200 operably configured to be selectively removably couplable to the first end 308 of the third body shell portion 116 in a watertight configuration. The plug 200 includes a portion 202 shaped and sized to be inserted within the enclosed aperture 314 of the third body shell portion 116. The plug 200 may be frictionally couplable to the third body shell portion 116, thereby causing the watertight configuration through compression of an outer surface 208 of the plug 200 with an inner surface 320 of the third body shell portion 116 that defines the plug entrance channel 322. In another embodiment, the plug 200 may include flanges disposed at the distal end of the plug 200 and the plug may be of a deformable polymeric material, e.g., nitrile rubber. When desired for replacement, the user will remove a third body shell portion 116 from the applicator 102, remove the plug 200 from a replacement third body shell portion housing a cosmetic substance, and then may couple the replacement third body shell portion to the second body shell 112 in a locked and watertight configuration, i.e., the replacement third body shell portion may not be freely removable from the second body shell 112. In some embodiments, the connection between the body shell portions 110, 112, 116 may include one or more gaskets facilitating the watertight connection.
Referring to FIGS. 2-3 in combination with FIGS. 6-7 and FIG. 9, the second opening 204 defined by the second end 108 of the applicator body 102, the enclosed aperture 314 defined by the bottom surface 312 of the third body shell portion 116, and the enclosed aperture 610 defined by the second body shell portion 112 may be axially aligned with one another about the longitudinal axis 900. Said differently, the opening 204 and apertures 314, 610 are disposed in an overlapping relationship with one another to cause effective translation of the applicator stem 700 within the body 102 and outwardly therefrom. In one embodiment, the second opening 204 may be selectively covered and sealed by the cover 104. In another embodiment, the second opening 204 may be defined partially or completely by a cap 206 selectively removably couplable to the third body shell portion 116.
More specifically, the third body shell portion 116 may also include a cap 206 operably configured to be selectively removably couplable to the second end 310 of the third body shell portion 116 in a watertight configuration. Like the plug 200, the cap 206 may include a portion 316 shaped and sized to be inserted within an enclosed aperture 318 defined by the second end 310 of the third body shell portion 116 in a watertight and substantially locked or retained configuration, e.g., using a frictionally engaged or tongue-and-groove configuration. The cap 206 may have the cover 104 selectively removably coupled thereto. The cover 104 may also be selectively retained and/or locked with respect to the cap 206 requiring a minimum level of force from the user to remove the cover 104 from the cap 206 (or the third body shell portion 116 if a cap is not utilized). The cap 206 beneficially the user to reuse the cap 206 and cover 104 with a replacement second body shell portion. In some embodiments, another plug may be utilized with the replacement second body shell portion, wherein said plug would be removed before use of the replacement second body shell portion.
